IMPROVEMENT IN CiDER-PRESSES.

Specification forming part 0f Letters Patent No. 215,483, (lated May:20, 1879; application filed January 31, 1878.

To all fwhom 'it may concern:

Be it known that I, MARcUs P. ScHENcK, of Fulton, in the county ofOswego and State of New York, have invented a certain new y and ImprovedCider-Press, of which the folnecting shaft or shafts, operated 'eitherby` power or by hand, as required.

My improvement particularly consists ina combination of stationaryscrews, press-beam,

Y wheels, nuts, recessed steps, and detached washer placed within thesteps to reducewear and friction; also, in the combination, with theaforesaid screws, beam, and nuts, of a levverand-ratchet movement foroperating the gearing, as hereinafter described.

In the accompanying drawings, Figure l is a front elevation of myimproved press.. Fig. 2 is a vertical section of one of the screw-nutsand attached gear-wheel on a larger scale. Fig. 3 is an elevation of theratchet-lever detached. Fig. el is a plan view of a rack of connectedslats to be interposed between the layers of material in the press. Fig.5 is a plan of a mat made of cords transversely arranged in successivelayers for a similar purpose.

A represents the base or bed of the press; B, the press-beam; C C', apair of stationary screws having a right and left thread, respectively,both of them fixed by nuts D D to the bed A, and projecting upwardthrough suitable apertures in the beam B. y

E represents a bridge-piece extending from one to the other ofthe screwsC C at the top, and serving to support a drivingsh aft, through whichthe machine is worked by means of a pulley, F, beveled pinion F',beveled gear G, and a vertical shaft, H, which is formed with either aspline or a groove, in which the hub of the gear-wheel Gr works, so asto impart rotary motion to the said shaft, while the latter slidesfreely up and down within the gear- Wheel as the press-beam is raised orlowered.

`beveled pinions 7c 7c, which drive beveled, wheels K K1, the hubs ofwhich form nuts K2,

as shown on a larger scale in Fi' 2, working on the vertical screws CC', and resting in recessed steps M M on the press-beam. The recesses orchambers of the step contain steel or brass washers N, which receive andreduce the friction of the lower vend of the nuts or hubs K2. i

By constructing the steps with recesses to receive the said Washers andthe lower ends of the hubs, the hub and nut and the step and washers areall held in concentric position, so as to protect the moving part-s fromany chafing of the screw.

rIhe loose pinions it are connected with the shaft I at the will of theoperator, so as to impart rotation thereto in either direction by meansof a clutch, L, operated by a lever, O, and connecting-rod P, andsliding on a suitablespline or groove in the shaft, so lthat when it isthrown into connection with the pinion i', as 'illustrated in Fig. 1,the shaft I will be driven by the shaft H in one direction, and when thesaid clutch is thrown into connection with the .pinion i the shaft lwill be rotated in the other direction, or by setting the clutch inintermediate position both pulleys it" will run loosely, and the shaft Iand nuts and pressbeam will remain at rest, while the power-conlnections F G H may run continuously. The

driven by beveled pinions r rl on a horizontal shaft, B, which isrotated in either direction by a haiid-lever, S, working over a ratchetwheel, r2, on the shaftR, and turning the said wheel in either directionby means of' an adjustable pawl, T, pivoted at s to the lever S, andhaving an elastic arm or lever, t, which may be set in either of thenotches u, ul, or u2 on the face of the lever S, in order that thereciprocation of the said lever may turn the ratchet-wheel r2 iu eitherdirection, so that it may be elevated or lowered or left at rest. Theconnections of the hand-lever are shown on a larger scale in Fig. 3.

In order to afford albearing for the presscloth, which will protect itfrom great violence or danger of tearing, and especiallyT from forcibleoutward pressure, I place between the cheeses a rack constructed, asshown in Fig. 4, of slats, V, connected by a webbing., r, or cloth oi'any kind. A rack thus constructed is readily rolled up fortransportation or for stowing away, and while in use not only fullyprotects the press-cloth, but affords perfect freedom of drainage forthe cider or other liquid running from the press.

I further employ for the same purpose a mat represented in Fig. 5,consisting of cords W W', laid in alternate coils in two layers, thecoils of one being transverse to the coils of the other, as shown.

X represents the customary platen or follower, upon which the press-beamrests through the medium of transverse beams x.

Y is the bottom board, resting on the bed A, and surmounted by thecustomary rack y. Z represents the press-curb, made of boards withnotched ends locked together.

For elevating the beam and supporting it from the nuts K2, I employbrackets or arms B2, securely bolted to the top of the beam B,

and engaging in grooves 7a2 in the periphery of the nuts or hubs K2.

Having thus described my invention, the following is what I claim as newand desire to secure by Letters Patent:

l. The combination of the wheels K K1, nuts K2, recessed steps M, andthe loose anti-fric tion washers N,placed in the bottoni of the recessedsteps beneath the nuts without attach nient thereto.

2. The combination oi' the` press-beam B, screws C C, wheels K Kl, nutsKZ, shafts H I, clutch L, and pinions h i i', substantially as and forthe purpose set forth.

MARCUS P. SGHENCK.
